Abstract:
The present invention relates to a method for controlling Septoria tritici on cereal plants, comprising treating the plants, their seed or the soil with a fungicidally effective amount of a composition comprising (a) pyraclostrobin or picoxystrobin as compound I; and (b) prothioconazole or propiconazole as compound II; wherein the Septoria ssp. are resistant to strobilurine fungicides.
Abstract:
The invention relates to a method for increasing the resistance of plants to the phytotoxicity of agrochemicals, said method being characterised in that the plants, the ground, or the seeds are treated with an effective quantity of a compound of formula (I), which is absorbed by the plants or seeds. In formula (I), X represents halogen, alkyl or trifluoromethyl; m represents 0 or 1; Q represents C(=CH-CH3)-COOCH3, C(=CH-OCH3)-COOCH3, C(=N-OCH3)-CONHCH3, C(=N-OCH3)-COOCH3, N(-OCH3)-COOCH3 or a group (Q1) wherein # characterises the bond to the phenyl ring; A represents -O-B, -CH2O-B, -OCH2-B, -CH=CH-B, -C °C-B, -CH2O-N=C(R1)-B oder -CH2O-N=C(R1)-C(R2)=N-OR3, wherein B represents phenyl, naphthyl, 5-membrered or 6-membered hetaryl or 5-membered or 6-membered heterocyclyl, the ring systems being unsubstituted or substituted according to the desciption; R1 represents hydrogen, cyano, alkyl, halogenalkyl, cycloalkyl or alkoxy; R2 represents phenyl, phenylcarbonyl, phenylsulfonyl, 5-membered or 6-membered hetaryl, 5-membered or 6-membered hetarylcarbonyl or 5-membered or 6-membered hetarylsulfonyl - the ring systems being unsubstituted or substituted according to the description - alkyl, cycloalkyl, alkenyl, alkynyl, alkylcarbonyl, alkenylcarbonyl, alkynylcarbonyl, alkylsulfonyl, or C(R')=NOR', the hydrocarbon radicals of said groups being unsubstituted or substituted according to the description; and R3 represents hydrogen, alkyl, alkenyl, alkinyl, the hydrocarbon radicals of said groups being unsubstituted or substituted according to the description.
Abstract:
The present invention relates to a method of inducing plant tolerance to harmful fungi comprising the application to the plants, the soil, in which the plant grows or is to be grown and/or the seeds of the plant, of an effective amount of an active compound that inhibits the mitochondrial breathing chain at the level of the b/c1 complex.
Abstract:
The present invention relates to the use of strobilurin type compounds of formula I and the N-oxides and the salts thereof for combating phytopathogenic fungi containing an amino acid substitution F129L in the mitochondrial cytochrome b protein (also referred to as F129L mutation in the mitochondrial cytochrome b gene) conferring resistance to Qo inhibitors, and to methods for combating such fungi. The invention also relates to novel compounds, processes for preparing these compounds, to compositions comprising at least one such compound, and to seeds coated with at least one such compound.

Abstract:
A method for controlling fungal pests which display a resistance to carboxamide fungicides consists of applying a fungicidally effective amount of a compound of the general formula (I), where -R means for example: formula (II) or formula (III), and where -X is either -Cl or -F, and where -Z- means for example a group: formula (III), preventively to the plants.
